Description

Technical Field

[0001] This utility model relates to the field of hardware die casting technology, specifically a die casting tooling that allows for quick replacement of hardware parts. Background Technology

[0002] Die casting equipment is a series of industrial casting machines that use pressure to inject molten metal into a mold, cool and solidify it, and then open the mold to obtain a solid metal casting. It is widely used in hardware processing.

[0003] However, in the die casting of hardware parts, the high temperature solution cools down slowly in the die casting mold, and it takes a long time before the mold can be opened and the parts can be removed, which reduces the efficiency of hardware die casting.

[0004] As disclosed in Chinese Patent CN219966405U, a multi-angle die-casting device for hardware parts is used. A high-temperature solution is poured into the inner cavity of the second mold, and then a cylinder is activated. The output end of the cylinder drives the lower end of the first mold to extend into the inner cavity of the second mold, ensuring a tight connection between the two molds and simultaneously die-casting the hardware parts. Afterwards, a water pump is activated, drawing cold water from the inner cavity of the cold water tank and transmitting it to the inner cavity of the distribution pipe. The distribution pipe then distributes the cold water to the inner cavity of the atomizing nozzle, which sprays the atomized cold water onto the surfaces of the second and first molds, thus achieving rapid cooling. Simultaneously, a motor is activated, and the motor's output shaft drives a turntable to rotate. The turntable then rotates the second and first molds, ensuring that both molds are fully sprayed with cold water mist, achieving comprehensive cooling.

[0005] However, in the existing technology, it is not convenient to quickly retrieve the hardware parts after die casting, which affects the efficiency of hardware die casting production and processing.

[0006] Therefore, we urgently need to provide a die-casting fixture that allows for quick replacement of hardware parts. Utility Model Content

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model. Example

[0027] Due to the inconvenience of quickly retrieving the hardware parts after die casting in existing technologies, which affects the efficiency of hardware die casting production, please refer to... Figures 1-2 The embodiment provides a die-casting fixture with quick-change hardware parts, which can effectively improve the material handling speed after the hardware parts are die-cast and thus effectively improve the efficiency of hardware die-casting. The die-casting fixture with quick-change hardware parts includes a base 1, a material handling device is installed on the top of the base 1, a cooling device is installed on the middle of the top surface and the back of the base 1, and a mold closing device is installed on the top of the material handling device.

[0028] The material handling device includes a tilting structure and a limiting support structure. The limiting support structure is installed at the bottom of the tilting structure. The tilting structure includes an asynchronous motor 102. The output end of the asynchronous motor 102 is connected to a transmission component 103. A rotating shaft 104 is installed in the middle of the transmission component 103. Two rotating shafts 104 are close to each other and connected to a lower mold 105 at one end. The limiting support structure includes a support frame 101. A limiting plate 106 is provided at the bottom of the middle part of the support frame 101. A limiting block 107 is installed at the bottom of the outer surface of the limiting plate 106. A support seat 108 is slidably connected to the outer surface of the limiting block 107.

[0029] The bottom end of the support frame 101 is fixedly connected to the left and right ends of the top surface of the base 1. The bottom of the asynchronous motor 102 is detachably connected to the left middle of the support frame 101. The rotating shaft 104 is installed on the left and right middle sides of the support frame 101 through bearings. The bottom surface of the support base 108 is fixedly connected to the top surface of the base 1. The limiting plate 106 is fixedly installed on the left and right sides of the lower mold 105 near the bottom end.

[0030] By setting up a material handling device, the asynchronous motor 102 is started to drive the transmission component 103 and the rotating shaft 104 to flip the lower mold 105, thereby quickly handling the die-cast parts and effectively ensuring the die-casting production efficiency of the parts.

[0031] After the hardware parts are die-cast, the asynchronous motor 102 is started to drive the transmission component 103. The output end of the asynchronous motor 102 drives the worm to rotate. The outer surface of the worm meshes with the worm wheel, and the inside of the worm wheel is connected to the rotating shaft 104. The rotating shaft 104 drives the lower mold 105 to rotate, thereby flipping the lower mold 105 and realizing the rapid unloading of the hardware parts formed inside the lower mold 105. During the flipping process, the limiting plate 106 and the limiting block 107 are slidably connected to the limiting groove in the middle of the top surface of the support base 108 to ensure the speed and accuracy of the flipping. During the die-casting process, the limiting plate 106, the limiting block 107, and the support base 108 provide auxiliary support for the lower mold 105. Example

[0032] Based on Implementation 1, existing technologies also have the problem that air inside the mold during the die-casting process can easily affect the die-casting effect, and the mold is not easy to cool quickly after die-casting. Please refer to [link / reference needed]. Figures 3-5 This embodiment provides a die-casting fixture for quick-change of hardware parts, which effectively solves the problem that internal air after mold closing can easily affect the die-casting effect, and that the die-cast hardware parts are not easy to cool quickly. This die-casting fixture for quick-change of hardware parts includes a mold-closing device including a hydraulic cylinder 201. The output end of the hydraulic cylinder 201 is connected to an upper mold 202. Positioning pins 203 are installed at the bottom ends of the left and right sides of the upper mold 202. An injection pipe 204 is installed near the left end of the top surface of the upper mold 202, and an exhaust pipe 205 is installed near the right end of the top surface of the upper mold 202. A memory spring 206 is installed inside the exhaust pipe 205, and a sealing block 207 is installed at the top of the memory spring 206. The hydraulic cylinder 201 is detachably installed in the middle of the top surface of the support frame 101. The bottom end of the memory spring 206 is fixedly connected to the inner wall of the exhaust pipe 205, and the outer surface of the sealing block 207 is slidably connected to the inner wall of the exhaust pipe 205.

[0033] The cooling device includes a collection box 301, with limit rods 302 connected to the middle of the left and right sides of the collection box 301. A liquid tank 303 is provided on the back of the collection box 301, and a semiconductor cooler 304 is installed in the middle of the back of the liquid tank 303. A fan 305 is installed in the middle of the front of the liquid tank 303. The bottom surface of the collection box 301 abuts against the middle of the top surface of the base 1. The limit rods 302 are fixedly installed on the middle of the two support seats 108 on one side close to each other. The liquid tank 303 is fixedly installed on the back of the base 1.

[0034] By using the mold closing device and cooling device, the memory spring 206 drives the sealing block 207 to slide inside the exhaust pipe 205, which facilitates the discharge of internal air after mold closing, effectively improving the processing quality. In addition, the fan 305 can quickly cool the molded hardware and the lower mold 105.

[0035] When the mold is closed, the hydraulic cylinder 201 is activated to drive the upper mold 202 to descend, so that the bottom surface of the upper mold 202 and the top surface of the lower mold 105 are closed. During the mold closing process, the positioning pin 203 is engaged with the positioning plates on the left and right sides of the lower mold 105 through the pin holes, so as to quickly close the mold. Then, molten metal is injected into the lower mold 105 and the upper mold 202 through the injection pipe 204, and the air inside the mold is discharged through the exhaust pipe 205. The temperature inside the mold increases, causing the memory spring 206 to extend. The memory spring 206 drives the sealing block 207 to slide away from the exhaust pipe 205, thereby effectively preventing the air inside the mold from affecting the die casting quality. Furthermore, after die casting, the collected parts are collected using the collection box 301, the semiconductor cooler 304 is activated to cool the coolant inside the liquid tank 303, and then the fan 305 is activated to quickly cool the formed parts and the lower mold 105, thereby facilitating the rapid forming of the die-cast parts.
